Beyond left and right: the Civil War roots of Irish politics
In short: While most democracies debate left versus right, Ireland’s political landscape was long defined by a different fracture. The legacy of the 1921 Anglo-Irish Treaty created a unique political divide, where the primary tension emerged not from economics, but from the bitter memory of a domestic conflict.
For much of the 20th century, Irish politics was characterized by 'Civil War politics' rather than a standard ideological spectrum. This division stems from the 1921 Anglo-Irish Treaty, which split the original Sinn Féin. The faction that supported the Treaty, Cumann na nGaedheal, eventually merged with other groups in 1933 to form Fine Gael. Conversely, members of the anti-Treaty faction who opposed the policy of abstentionism broke away to found Fianna Fáil in 1926, led by Éamon de Valera.
This split fueled the Irish Civil War from 1922 to 1923 and established the dominance of the two parties, often pejoratively called 'FFG'. Fianna Fáil, once a radical party of small farmers and urban workers, has since become a pillar of the establishment, holding the largest number of Dáil seats and council seats as of 2024. Fine Gael remains a significant force, historically leading coalitions with the Labour Party for much of the period between 1948 and 2016.
Today, the landscape is diversifying. While Fianna Fáil remains the largest party in Dáil Éireann, Sinn Féin has risen to second place. Other players like the Social Democrats, the Green Party, and the Labour Party—which has been active since 1912—contribute to a complex parliamentary structure. The modern system is increasingly defined by coalitions, as single-party governments have become rare since 1989, and new entities like Independent Ireland and Aontú continue to shift the traditional balance.
